CURTAIN-FIXTURE.

SPECIFICATION forming part of Letters Patent No. 308,038, dated November 11, 1884.

' Application filed July Q3, 18H3. (No model.)

To @ZZ wle/0m it may concer/t:

Iing from the periphery at right angles to its Beit known that I, JAMES M. OSGOOD, a face, having a Vcentral aperture, a, therein,

citizen of the United States, residing at Somerville, in the county of Middlesex and State of Massachusetts, have invented a new and useful Curtain-FiXturc, of which the following is a specification.

My invention relates to improvements in spring-curtain xtures in which the catch operates upon the spindle and locks directly into the cap or ferrule upon the head of the roller. I attain these objects by the mechanism illustrated in the accompanying drawings.

Figurejl shows the spindle end of the roller with ferrule attached. Fig. 2 is a longitudinal section through the center of the roller. Fig. 3 shows tryo methods of making notched projections on the spindle.. Fig. 4 is the cap end ofthe ferrule. Fig. 5 shows a perspective View ofthe spindle and catch. Fig. 6 is a face and top view of catch. Fig. 7 is a longitudinal section ofthe ferrule, showing position of catch when in operation. Fig. 8 shows portion of catch upon the spindle.

All figures are double size. except Fig. 5.

Similar letters refer to similar pa-rts throughout the several views.

'A is the spindle end of the fixture passing intot-he bored end ofthe roller.

B is a ferrnle pressed rmly in the end of the roller. This ferrule is made with two holes in the face of it, as is shown in Fig. 7, the face part ot' the fcrrule being made about double the thickness of the sides, for the purpose of forming a secure hold for the catch.

Fig. 2 shows each part of the invention when in operation. The catch G rests on the spindle A with the tooth of the catch projecting through the face of the fcrrule B.

.When the roller is revolved, the tooth is forced out of the hole by the catch being tipped from its perpendicular resting upon an angle or on one edge. When the roller is stopped, the catch drops back into perpendicular, the tooth again locking into the face of the ferrule B, as before, thereby holding the tension of the spring. By this method of holding the force of the spring the usual capis dispensed with. The ferrule as here used answers for both cap and ferrule. The catch Gis made disk shape, with its tooth or flanged portion c projectthe curtain is being pulled down.

and provided with lateral slots s, through which central aperture, a, the spindle passes,

said catch being held. loosely upon its spindle, as shown in Fig. 5, to obtain a tilting motion,

` while it is prevented from axial motion by radial projectionsp upon the spindle, which enter the lateral slots sin said catch. The spindle-end projectionsl and not-ches are made of one piece of metal.

Fig. 6 is a face and top view of the catch C, which has a hole through its center sufficiently large to allow a free movement. The tooth or flanged portion c of catch C is provided at one side with an abrupt shoulder locking into lthe ferrule, while the opposite shoulder is beveled to permit the tooth to be Withdrawn from the slot x of the ferrule When The catch setswithin the bore of the roller, which makes a chamber to operate in.

Having described my invention, what I i claim as new, and desire to secure by Letters Patent, is-

1. In a curtaiirroller, the combination of spindle A, having lateral projections p, with a disk-shaped catch, C, provided with atooth or lianged portion, c, and a central aperture, a, and lateral slots s, loosely mounted on the spindle to have a tilting action, and the ferrule B, with which the pawl or catch C engages, substantially as set forth.

2. In a spring curtain-roller, the combination of spindle A, provided with lateral projections 19, with the pawl or catch G, loosely fitted thereon, and the combined ferrule and4 end cap, B, having locking-aperture x, substantially'as Shown and described.

3. In a spring curtain-roller, the combination of spindle A, provided with lateral projections p, the pawl or catch C, loosely fitted thereon, and the end cap or ferrule, B, having locking-apertures x, the pawl being located within the bore of the roller and the ferrule, substantial] y as set forth.
